10.6.7
If an input capture signal and counter increment signal occur simultaneously, the counter is
cleared according to the input capture signal. The counter is not incremented by the increment
signal. The TCNT value before the counter is cleared is transferred to the general register. The
timing is shown in figure 10.64.
